5.0 Task 3: Assessing Network Utilization

Vivinet Assessor determines whether your network is VoIP-ready by gathering and assessing utilization statistics for the devices and links on your network. Before you try to assess utilization, you must first perform a Network Inventory to ensure that the devices and links to be queried are already in the database when you commence utilization monitoring. For more information, see Section 3.0, Task 1: Performing a Network Inventory.

Vivinet Assessor cannot monitor every conceivable router or switch on a given network. The following table summarizes the supported devices:
